MACHINE FOR ASSEMBLING RADIATOR-LOOPS.

SPECIFICATION forming part 01' Letters Patent No. 38 6. dated April 3. 18

Application filed December 'I, 1887.

To all whomit nmy concern:

Be it known that I, HAnnIsoN H. TAYLOR, a citizen of the United States, residing at Detroit, county of Wayne, State of Michi gan, have invented a certain new and useful Improvement in Machines for Assembling Radiator-Loops; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawingswhich forma part ofthisspecification.

My invention consists of the combination of devices and appliances, hereinafter specified, and more particularly pointed out in the claims.

In the drawings, Figure l is a plan view of a machine embodying my invention. Fig. 2 is a side elevation of the same upon the side adjacent to the levers. Fig. 3 is an end view of the same adjacent to the gearing. Fig. 4is a detail view of the ratchet mechanism for setting the radiator back to receive a newloop. Fig. 5 is a detail view of the chuck on a traveling carriage. Fig. 6 is a detail view of the chuck adjacent to the gearing. Fig. 7 is a face view of the arm which revolves the radiatorloop as it is screwed onto its seat. Fig. 8 is a view of the separating wedge-block.

It is the objectof this invention to produce a machine which shall assemble the loops of a cast'iron radiator, the said radiator being of that type in which the loops are each provided with a hub at the base and are screwed each one to the adjacent one either directly or upon an interposed screw-threaded nipple.

This operation has heretofore been accomplished by hand, and has required very con siderable time and labor and involved a corresponding expenditure.

In carrying out my invention,A is asuitable frame-work.

B is a chuck which is adapted to travel back and forth along the guide or way 0. This traversing of the chuck may be effected in any convenient way. Thus, for instance, the pinion a may engage a rack-bar, A, on the side of the frame, so that by turning the pinion in one direction or the other the chuck to which Serial No.251257. (No model.)

the pinion is journaled is caused to travel in a corresponding direction. The mechanism which I have employed for this purpose is illustrated in Figs. 2 and 4 of the'drawings, in which a is a leverjournaled freely on the axis of the pinion a. On the face ofthis lever is a pawl, a which engages the notch or ratchet wheel a, fixed at the end of the pinion-shaft. This pawl is held in contact with the ratchet. wheel a. by a plunger, a, and a spring, a The pawl a has two engaging-detects, so that it may operate the ratchet in either direction according as the one or the other detent is in contact with the ratchet.

a is a pivoted dog on the side of the chuck B, which may be thrown into engagement with the rack A, and so hold the chuck from any further motion in a direction away from the radiator. So, also, the particular deteut on the pawl in contact with the ratchet-wheel will depend upon the location of the point of the plunger (6 with respect to the adjacent point of the. pawl. This plunger a may be brought to either position by simply pressing back its spring a, as is clearly indicated in Fig. i.

Through the chuck 13 passes freely a bolt,

B, threaded at its extremity and of a size adapted to enter the tapped orifice in the hub of the adjacent radiator-loop. Such a radiator-loop is shown at D.

E is a stationary head'or sleeve, in which is journaled the shaft E. At one end of this shaft is fixed the lever E,which engages each successive loop and revolves it about its hub as a center, so as to screw it to the adjacent loop. On the other extremity of the shaft E is the gear-wheel E". This meshes with an elongated pinion, F, and by the intermediate gears, F F", the same is connected with the drive'shaft Fiwhich is provided with fast and go loose pulleys 1i and F respectively, a lever,

F, serving to operate the beltshifter F so as to throw the belt at will onto the tight orloose pulley,whereby the machine is thrown into or out of operation.

Returning now to the shaft E, this shaft is itself hollow, and through it passes a bolt, c,

provided at its head with a crank to facilitate turning the same, and at its extremity the bolt is threaded, and is of a size to engage the too threaded orifice in the hub of the loop D, which is to be Connected into the radiator.

A lever, G, serves to operate a shifter, G, whereby the gear-wheel E is shifted in or out in a direction longitudinally of its axis.

The operation of the device will now be understood.' The operator,wishing to assemble the loops into a radiator, takes the first loop, places it on the frame of the machine in the position shown in Fig. l at D. He then runs the screw B into its hub 'until he binds the said loop firmly against the chuck B. He then brings the lever or arm E" into the position shown in Fig. 1, and lays upon the lugs e the next loop D with its hub opposite the extremity of the bolt 6. This bolt is then screwed into the orifice in the loop until this loop is firmly bound against the face of the le ver E Then with the lever G the gear-wheel E and its shaft E are thrown forward, carrying the lever E and its loop into proper position, so that the nipple (1 upon the loop D" will properly enter the adjacent hub. Then with the lever B the operator shifts the belt from the loose pulley onto the tight pulley, the machine is at once set into operation, and the lever E with its loop, is caused to revolve until the loop is screwed firmly to its seat.

H is a separating wedgc-block,which is put over the last loop that is in position, so that when the next loop is screwed nearly home it may slightly deflect the same at its extremity, so that it will not strike against the loop that has been already screwed down to its place. After thisloop has been thus brought into its place the belt is again thrown onto the loose pulley, the bolt 6 is then run out from the hub of the loop, and with the leverG the shaft E and lever E are again thrown back and a new loop is added, as before. This is continued until the loops are all assembled.

I would have it understood that this mechanism may be considerably varied without departing from my invention. Thus, for instance, other means might be employed for communicating motion to the driving parts of the machine. So, again, the shaft E and rotating lever E might be arranged to be moved axially forward and back without shifting the gear-wheel E So, also, any other convenient means might be employed for holding the loop D to the chuck B. So, also, other means might be employed for holding the loop D to the rotary lever E. In fact, the mechanism may dispense with any means for engaging the hub of the loop adjacent to said lever,

and the machine is sometimes so employed. So, also, the chuck B might be simply a stationary support and the lever E be caused to recede as new loops are added until the loops have all been assembled. All changes of this character are within the province of an ordinary mechanic and would be what I would regard as equivalent constructions.

I am not aware that a machine was ever before made for assembling radiator-loops, but that heretofore they have always been assembled by hand.

What I therefore broadly claim is- 1. A machine for assembling radiator-loops, consisting ofa revolving lever or support with means for driving the same, said lever or sup port adapted to revolve about the axis of the hubs to be united as a center, and another support adapted to hold in proper position the loop or loops already assembled to which the new loop is to be applied, substantially as and for the purpose set forth.

2. In a machine for assembling radiatorloops, the combination of a support for bold ing the first loop or loops to which the new loop is to beapplied,a revolving lever or support for the loop to be applied,with means for revolving the same, and mechanism for causing one of said supports to approach the other, so as to engage the threads of the new loop with those loops already assembled, substantially as and for the purposes set forth.

3. In a machine for assembling radiatorloops, a support adapted to hold the first loop, said support provided with means for moving it and its loop or loops to the rear to make place for new loops to be added, substantially as and for the purposes described.
